International. This is the ERVi, a solution designed by Greenheck to adapt to limited indoor spaces, such as basements, mezzanines and small machine rooms.
Its modular construction fits through a 30-inch door, can be hung from the ceiling, and is ideal for modernization and decarbonization projects. It is highly configurable, with access from the right or the left, and discharge from either end.
Two compact enclosure options are available: the ERVi-10 discharges between 375 and 1500 cfm with a maximum height of 18 inches, while the ERVi-20 discharges between 750 and 2500 cfm with a maximum height of 23 inches.
The ERVi includes a 3-inch polymer enthalpy wheel, a direct-drive fan, an electronically commutated motor, and full factory controls with a DDC microprocessor. It has a solid construction, with an inch of injected foam and a Permatector-painted exterior.
Optional features include factory-installed low-leakage dampers, downstream heating and cooling control, frost control and economizer and MERV 13 filters.
The enthalpy wheel, which helps the ERVi provide more outside air for less by recovering energy from exhaust air, can also be configured as high-effectiveness or high-flow.
